The working specification depends on the type and wall
thickness of the tube, the type of fluid, fluid temperature,
and ambient temperature.
technical specification
The LF 3800 range extends the advantages of push-in fittings -
instant connection and disconnection – to a wider range of
industrial applications.
All stainless steel construction with FKM "O" ring seals, LF 3800
offers excellent resistance to aggressive environments and
fluids ;
To suit most applications, models are available :
- for metric tubing with BSP taper thread, BSP parallel thread
and metric or NPT threads;
- for imperial o.d. tubing with NPT thread.
Maximum 20 bar depending on tubing used
(see section on Legris tubing)

non-return valves, all fluids and stainless steel
Legris stainless steel non-return valves allow fluids to pass in
one direction whilst blocking flow in the other direction. Robust
and extremely compact, they are suitable for use as a safety
item in all fluids circuits. They are ideal for use in severe
conditions and in aggressive environments.
Operation : a stainless steel valve blocks the fluid passage,
when the pressure differential is lower than 0,25 bar.
